Working principle of air cooler

The cooling principle of the air cooler (evaporative air conditioner) is: When the cold wind during into the cavity to produce negative pressure, make clear wet curtain air through the porous moist surface force of the curtain air dry bulb temperature dropped to close to the outside air wet bulb temperature, the cooling fan export the dry bulb temperature of 12 ℃ lower than outdoor dry bulb temperature of 5 - (dry areas can reach 15 ℃), the dry air, the temperature difference is big, the better the cooling effect. Because the air is always from the outdoor into the indoor, (this time called the positive pressure system) so it can keep the indoor air fresh; At the same time because the machine uses the evaporation cooling principle, so it has the dual function of cooling and humidifying (the relative humidity can reach about 75%), in the textile, knitting and other workshops, not only can improve the cooling and humidifying conditions, but also can purify the air, reduce the needle yarn breaking rate in the process of knitting, improve the quality of needle textile products.

Cold wind mechanism cold effect

The air cooler can not be compared with the capacity of large air volume refrigeration of air conditioning, but the price is lower, relative to the price of 10% to 20% of air conditioning, power consumption is only about 2% of air conditioning, so it still attracts many consumers. In different areas of China, the use effect of cooling fans is different, but the cooling effect is better than ordinary electric fans, reducing at least 3~8℃. The hotter the weather, the more obvious the cooling effect, the stronger the wind, the better the cooling effect.

Energy saving and environmental protection of the air cooler can bring a fresh air for the workshop of the enterprise and public places, as well as commercial entertainment and other places, but also can completely reduce the temperature. This kind of product is characterized by no compressor, no refrigerant, no copper pipe, and its main core is evaporative wet curtain. The 1.1kW main motor is an eighth of the power consumption of a traditional central air conditioner, making it a must-have for companies.

Air cooler air distribution pipe, air conditioning air supply pipe is also called high temperature resistance exhaust pipe, high temperature resistance exhaust pipe, this is just the name of the use of the industry. The structure of air duct is outer steel ring structure, wear resistance and negative pressure resistance; Fireproof Kevlar material; Protected by a strong steel ring, it can be dragged freely on the ground without wearing out the duct.

The main properties of air duct and air conditioner are:

1, powder metallurgy special high temperature coating

2, good heat resistance

3, high scalability and compression ratio of 4:1

4 External wear protection through spiral stainless steel (VA)

5, the external steel wire tightly clamp the tube wall, anti-bonding

6, good alkali metal and acid resistance, excellent chemical resistance

7. It has good resistance to ULTRAVIOLET and ozone

8, tube wall bending radius is small, not easy to knot, light weight

1, environmental protection air conditioning in the social application of dense or short time and need to quickly cool places, such as: auditorium, conference room, church, school, canteen, gymnasium, exhibition hall, shoe factory, clothing factory, toy factory, vegetable market, etc.;

2, there is heating equipment or high temperature production places, such as: mechanical processing, injection molding, electroplating, metallurgy, printing, food processing, glass, household appliances and other production workshops: shopping malls, supermarkets, amusement parks, casinos, waiting rooms; Suitable for agricultural scientific research and cultivation center or base.

3, there are places with strong smell of polluting gas and large dust, such as: hospital hall, waiting room, kitchen and chemical plant, plastic factory, electronics factory, chemical fiber factory, leather factory, spraying screen printing factory, rubber factory, printing and dyeing factory, textile factory, breeding factory and so on.

Industrial fan and negative pressure fan have a similar role, that is, cooling and dehumidification, so, people will be some hesitation in the choice, do not know which one to choose, in fact, industrial fan and negative pressure fan in the function similar or there are some differences, understand the difference between the two, we can choose according to their own needs, then, Industry what are the difference between big fan and suction fan? Jiaxing and below small make up answers, hope to be of help.

Industrial difference between fan and suction fan

1, installation is different

(1) Industrial fan installation. Big fan industry general installation at the top of the workshop and workshop working range is wide, so make the very big part of the area can be cool.

(2) Installation of negative pressure fan. Negative pressure fan general door installed outside the window of the shop, next tuyere installation, convenient outside convulsions.

2. Different principles

(1) Industrial fan principle. The cooling principle of the industrial fan is that the air flow from the top to the bottom into a cone to the ground, to the ground along the horizontal direction of the flow, meet the side barrier or the horizontal airflow near the fan to push up to the roof, can achieve effective full range of overall ventilation and effective cooling of personnel, the environmental requirements are not high not closed space can also effectively cool.

(2) Working principle of negative pressure fan. When the fan is energized to work quickly to achieve large exhaust air volume. Can make indoor environment quickly and produce a outdoor air pressure difference, form a powerful negative pressure, forcing indoor pollution hot air must be in the direction of the flow we set emitted quickly, in indoor air pressure drop.

3. Different effects

(1) industrial fan effect. In terms of personnel cooling. The natural breeze generated by the large energy-saving fan blows on the human body, promoting the evaporation of sweat to take away the heat, while cooling the human body, bringing the feeling of cooling. Usually, the cooling sensation can reach 5-8℃. In the aspect of natural ventilation, industrial fan can accelerate the indoor air flow, to achieve the effect of natural ventilation; In terms of desiccant moisture, dehumidifying effect of industrial fan, direct and effective, it promotes the whole space air mixture.

(2) Negative pressure fan effect. The air temperature in places requiring ventilation is higher than that outdoors because the sun shines on buildings, machines, equipment, and human bodies. The negative pressure fan can discharge the indoor hot air quickly, so that the room temperature and the outside temperature is flat, so as not to increase the temperature in the workshop. Negative pressure fan only ventilation cooling function, no refrigeration function, cool is the feeling of the human body.

4. Different places of use

(1) Industrial fan use place. Shopping malls, stadiums, stations, airports and other large public buildings, promote air circulation, dispel odors, create a comfortable shopping and viewing environment, increase sales. And big fan of mobile industrial fan can be used in a more open place, use rise more convenient also.

(2) Use place of negative pressure fan. Such as garment factory, electronics factory, entertainment venues, pig farm, garden flowers and so on need to be closed cooling and humidity.
